AIR PURIFICATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC B01D47/04 B01J8/24 

FIELD: gas processing.

SUBSTANCE: invention relates to techniques for liquid gas processing using periodic discrete processes, and therefore can be used mainly for household devices (air purifiers-humidifiers, vacuum cleaners), as well as in the food, chemical and other industries. The method of air purification is to place a hollow module with slots in its lower part inside the tank. The flow of gas-liquid suspension is directed into the inside of the hollow module. Next, the flow passes through a frame consisting of two fine-mesh meshes and a nozzle. Then the gas-liquid suspension is directed into a frame with a coarse mesh fixed inside the hollow module. The air purification device contains a housing, a pipe for inputting dust-laden air, a pipe for purified air extraction, and a reservoir with liquid. A hollow module with slots in its lower part is installed inside the liquid reservoir with a gap from the bottom of the liquid reservoir. Inside the hollow module there is a frame consisting of two fine-mesh meshes, the space between which is filled with a nozzle. A frame with a coarse mesh is fixed above a frame made of fine mesh with an attachment. The outlet pipe is equipped with a splash screen.

EFFECT: improved efficiency and reliability of the process of air purification from dust and other harmful impurities.
